completed a 5-mile trail loop today, and fell several times on the gravel 
section of the trail, going a little too fast ~10mph. The BMX tires probably 
played a part. Mountain bike tires should help, elbow pads and old jeans also. 
However, slowing down is probably the more sensible thing to do...  Dirt 
surface 
was fine, and so was asphalt. Otherwise, the 20" wheels are more stable and 
efficient than 16" Mini Python and 10" μPython.

Unfolded and crashed pictures are uploaded.  Didn't think that it would flip 
upside down; looks bad...

Great! A picture of the unfolded bike would be good too ...

Thanks,
Jürgen.
